Article Abstract
Introduction: We have recently developed a new miniaturized device for extracorporeal ultrafiltration (UF) to be used in patients with fluid overload: Artificial Diuresis-1 (AD1) (Medica S.p.A., Medolla, Italy). The device has a reduced priming volume, operates at very low pressures and flow regimes, and is designed to perform extracorporeal UF at bedside. After accurate experiments were carried out in vitro, we report in this paper the results of in vivo UF sessions carried out in selected animals according to veterinary best practice.
Materials And Methods: The AD1 kit is pre-filled with sterile isotonic solution and operates with a polysulfone mini-filter, MediSulfone (polysulfone at 50,000 Dalton). A collection bag with a volumetric scale is connected to the UF line, and the ultrafiltrate is obtained by gravity based on the height at which the ultrafiltrate collection bag is placed. Animals were prepared and anesthetized. The jugular vein was cannulated with a double-lumen catheter. Three 6-h sessions of UF were scheduled with a target fluid removal of 1,500 mL. Heparin was used as anticoagulant.
Results: In all treatments, the target value of UF was obtained in the absence of major clinical or technical problems with a maximum deviation from the scheduled UF rate lower than 10%. The device resulted to be safe, reliable, accurate, and easily usable thanks to a user-friendly interface and its very small dimensions.
Conclusions: This study opens the way for clinical trials in different settings including departments with low intensity of care and even in ambulatory centers or patient's home.

Electroactive bacteria (EAB) hold great promise for the development of electrochemical biosensors given their unique ability to transfer electrons extracellularly via specialized pathways, a process termed extracellular electron transfer (EET). Ongoing research aims to overcome current limitations and fully harness the potential of EABs for high-performance biosensing applications. Herein, we report the fabrication of an electrochemical microsensor based on biomineralized electroactive bacteria, specifically MR-1.

Acute lymphoblastic leukemia (ALL) is the most common hematologic malignancy in children. Current clinical diagnosis primarily relies on invasive detection methods, while molecular subtyping remains a complex and time-consuming process. This study innovatively employed silver nanoparticle-based surface-enhanced Raman spectroscopy (SERS) technology to systematically analyze 116 serum samples, including those with breakpoint cluster region-Abelson (-) fusion genotype, mixed-lineage leukemia (, also known as lysine methyltransferase 2A, ) gene rearrangement subtype, T-lymphoblastic ALL, and healthy controls.

Single-cell surface-enhanced Raman scattering (SERS) has emerged as a powerful tool for precision medicine owing to its label-free detection, ultrasensitivity, and unique molecular fingerprinting. Unlike conventional bulk analysis, it enables detailed characterization of cellular heterogeneity, with particular promise in circulating tumor cell (CTC) identification, tumor microenvironment (TME) metabolic profiling, subcellular imaging, and drug sensitivity assessment. Coupled with microfluidic droplet systems, SERS supports high-throughput single-cell analysis and multiparametric screening, while integration with complementary modalities such as fluorescence microscopy and mass spectrometry enhances temporal and spatial resolution for monitoring live cells.

Retinal ganglion cells (RGCs) are highly compartmentalized neurons whose long axons serve as the sole connection between the eye and the brain. In both injury and disease, RGC degeneration occurs in a similarly compartmentalized manner, with distinct molecular and cellular responses in the axonal and somatodendritic regions. The goal of this study was to establish a microfluidic-based platform to investigate RGC compartmentalization in both health and disease states.
